Boat handling apparatus



April 19, 1932. o CARLSON BOAT HANDLING APPARATUS Original Filed Jan.22, 1929 Patented Apr. 19, 1932 OTTO CARLSON, OF ASTORIA, OREGON BOATHANDLING APPARATUS Application filed January 22, 1929, Serial No.334,288. Renewed September 18, 1931 My invention relates to apparatusfor lowering or raising boats, such as life boats, from a ship.

In accordance with my invention, apparatus is provided, which may beemployed to lower a boat, such as a life boat, from a ship. When theboat being lowered rests upon the water, the boat is automaticallydisconnected from the lowering unit. In the event that either the bow orstern should first engage the water, and hence the automatic releasingaction be impaired or prevented, such action may be manually effected bythe operator within the boat. The apparatus is of simple construction,strong and durable.

In the accompanying drawings, forming a part of this specification, andin which like numerals are employed to designate like parts throughoutthe same,

Figure 1 is a side elevation of apparatus embodying my invention,

Figure 2-is a transverse section taken on line 22 of Figure 1,

Figure 3 is an enlarged side elevation of one of the releasing hooks,

Figure 4 is an edge elevation of the same,

Figure 5 is a side elevation of a modified form of releasing hook, and,

Figure 6 is an edge elevation of the same.

In the drawings, wherein for the purpose of illustration, are shownpreferred embodiments of my invention, attention being called first toFigures 1 to 4, inclusive, the numeral 10 designates a boat, such as alife boat, having a keel 11.

The hoisting or lowering unit embodies a rod 12, which may be square incross section, round, or of any other suitable shape. I prefer to mountsheaves 13 directly upon the rod 12 and the pulleys in these sheaves areengaged by tackle ropes let, which are at tached to the blocks upon thedavits, as is well known.

Arranged within the boat 10 are stanchions or uprights 15, each of whichis preferably formed of a pair of strap irons 16, bolted or rivetedtogether, as shown at 17. The lower ends of these strap irons areapertured to receive a bolt 18, also passing through openthe hooks arefreed ings in a generally U-shaped strap 19, which ispassed about thekeel 11.

The stanchionor upright 15, may remain permanently vertical or may befolded downwardly to a horizontal position, when not in use, Thestanchion 15 tothe left, Figure 1, may be retained permanently verticalby means of a strap 20, passing about the same, and attached to a .seat21, or other fixed part of the boat. The stanchion 15 to the right,Figure 1, may be swung downwardly upon the pivot 18, when not in use,and when this is desired the strap 20 is omitted, and the 1 stanchionoperates between a pair of seg-- mental guides 22. V

The'strap'irons 16, attheir tops, are bent laterally or spread,affording spaced arms 23. These spaced arms carry outwardly projectinglower stationary hooks 24, Figure 3, equipped with resilient extensions25, attached thereto. Arranged above the stationary hooks 24 are pivotedhooks 26, carrying depending resilient extensions 27. The hooks 26 areformedtintegral with a rock shaft 28, which is rotatably mounted withinopen ngs 29, in the spaced arms 23. The upper hooks 26 normally depend,and are in alignment with the hooks 24. The upper and lower hooks withtheir resilient extensions 25 and 27 provide sockets for receiving andholding the rod 12.

' Arranged between the upper ends of the arms 23 are weights 30, rigidlymounted upon the rock shaft 28, and sufficiently heavy to overcome theweight of the hooks 26, when w from engagement with the rod 12.

These weights are provided in their lower ends with apertures forreceiving and attaching a cord or cable 31, passed about pulleys 32. Thecord extends longitudinally of the boat adjacent to the keel. pullingthe cord,fthe weights 30 may be swung downwardly, and the hooks 26manually turned to the upper position, thereby releasing the, rod 12. InFigures. 5 and 6, I have shown a modification of the attaching unit orstanchion. The stanchion or' upright in these figures embody a pair'ofstrap irons 33, having the spread or spaced arms 34. The arms 34 carryoutwardly projecting fingers 35, equipped with upstanding resilientextensions 36. Co-acting with the lower fingers 35 are upper stationaryfingers 37, carrying resilent extensions 38. Arranged above the fingersor extensions 37 are pivoted hooks 39, carried by a rock shaft 40,pivoted within openings in the upper ends of the arms 34.

A weight 41 is rigidly attached to the rock 7 shaft 40, and is arrangedbetween the arms 34. The weight 41 is heavier than the hooks 39 and willraise the hooks, when they are freed from engagement with the rod 12.The numeral 42 designates a cord or cable, attached to the weights 40,and corresponding to the cord or cable 31.

In the operation of the first form of the invention, as shown inFigures1 to 4, inclusive, the rod 12 is arranged within the sockets beneath thedepending pivoted hooks 26. As the weight of the boat is now carried bythe hooks 26, the weights 30 can not turn these hooks upwardly. The boatmay now be lowered in the usual manner, and if it strikes the water, ata level, the rod 12 will move downwardly and relieve the engagementbetween the rod Y12 and the hooks 26. The weights 30 will nowautomatically swing downwardly, swinging the hooks 26 upwardly and therod 12 will be disengaged from the hooks. Should either the bow or sternfirst engage the water, and it is desired to release the boat, theoperator within the boat pulls the line 31, thereby manually turning theweights 3O downwardly and raising the hooks 26. This form of apparatusmay be used in both raising and lowering the boat.

In Figure 5, the operation of the pivoted hooks 39 is the same as thatof the hooks 26. The fingers or extensions 35 and 37 provide separatemeans for raising or otherwise handling the boat, when it is not desiredto use the pivoted hooks 39.

It is to be understood that the forms of my invention, herewith shownand described, are to be taken as preferred examples of the same, andthat various changes in the shape, size and arrangement of parts, may beresorted to without departing from the spirit of my invention, or thescope of the subjoined claims.

Having thus described my invention, I claim 1. In a boat handlingapparatus, a stanchion embodying a pair of strips secured together andspread at their ends for producing spaced arms, a rock shaft pivotallymounted upon the spaced arms and carrying hooks arranged upon oppositesides of said .arms, a weight arranged between the arms and rigidlymounted upon the rock shaft, and lateral extensions carried by said armsand co-acting with said hooks for producing sockets for the reception ofrods or the like.

connected with the rock shaft, and lateral ex- 5 tensions carried by thearms and co-acting with the hooks to produce sockets for receiving rodsor the like.

In testimony whereof I aflix my signature.

OTTO OARLSON.
